Answer:
The correlation coefficient of the data is 0.8679.
Step-by-step explanation:
The formula to compute the correlation coefficient is:
From the data provided compute the values of ∑ XY, ∑ X, ∑ Y, ∑ X² and ∑ Y².
The values are computed in the table below.
Compute the correlation coefficient as follows:
Thus, the correlation coefficient of the data is 0.8679.
Answer:0.64
Step-by-step explanation:
The moderate negative correlation cannot be close to zero or -1
Answer:
if a, b, and c are an integer such that ax+b/cx+d= 54x^2-150/18x^2+60x+50 find b/c
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use the exponential growth formula
Where A is the final amount in the account, P is the initial amount, r is the growth rate and t is the time in years
In this problem
We know that
So
Finally after 5 years the balance of the account is:
Answer:
A
Step-by-step explanation:
Slope intercept form is y=mx+b, where m represents slope and b is the y intercept. So, A would be the correct answer. Hope this helped!
